It seems that even with less functionality on the motherboards than socket 1156 motherbaords it seems that socket 1155 motherboards are still not cheap.
The cheapest socket 1155 motherboard I can find ATM is £68:

The motherboard has two RAM slots and is mATX. However it does have SATA3.0!
If you want to overclock you will need to get a P67 motherboard and the cheapest one seems to be around £90:

Hopefully, over the next few weeks prices will drop.
It seems the days of cheap Intel motherboards are long gone with the decline of socket 775.
